Probability Checkpoint

1. P(A or B) for mutually exclusive events is:

P(A) + P(B) P(A) * P(B) P(A) - P(B) P(A) / P(B)

2. Bayes' theorem relates:

Prior and posterior probabilities Mean and variance Population and sample Loss and accuracy

3. The probability of all outcomes in a sample space sums to:

1 0 Infinity Depends on the space

4. Name a common discrete probability distribution.

5. P(A|B) means:

Probability of A given B occurred A and B together A or B A causes B
